Can you reload a program without resetting the variables?

I am working on the intro to javascript game, and I knew a little more than was taught, so I went farther with the game, making the coins and poison and other items randomly spread on the page. Now, I am trying o make it so that when you win, the currentScore is reset, the winningScore increases by ten, the level increases by 1, and the rest of the program is rerun so the poison and stuff is in different positions. I tried window.location.reload(); but it reset all to variables when it reloads, so it makes you replay the same level over again. Is there a way to keep like 3 lines of code from reloading when the rest of the program reloads?

Here is the code for when you win: if (won) { won = false; nextLevel = true; } if (nextLevel) { window.location.reload(); winningScore += 10; currentScore = 0; level++; }
